AMD's budget Ryzen motherboard chipset, the A520, has largely slipped under the radar. While B350 and B450 motherboards were mostly regarded as being entry level, A320 was strictly seen as resolutely low end.
The introduction of B550 motherboards, and their associated move upward in price, left a big hole in the sub-$100 market. Enter A520. If you’re on a tighter budget, and don’t care about PCIe 4.0 or the overclocking support offered by B550, then the A520 motherboards might be exactly what you need. There’s cheap and there’s really cheap, but a decent A520 board can more or less do everything a board at double the price can.
You could grab an Nvidia RTX 3080, a top spec NVMe SSD , and 32GB of DDR4-3600, and use them all with an A520 motherboard. That would be an unlikely combo, but would remain a high performing one nonetheless.
And compare A520 to Intel’s B460 motherboards for a minute. You can run memory speeds at well above B460’s DDR4-2666 or 2933 hard limit, and you’re less likely to run into VRM heating issues thanks to the more power thrifty nature of Ryzen CPUs.
Then there’s the cherry on top which is support for the upcoming AMD Ryzen 5000 series and, almost as importantly, Ryzen 4000 series APUs. Combine a Zen 3 CPU with a motherboard such as this ASRock A520M ITX/ac and you’ll be able to build an affordable and compact system that—if AMD is to be believed—may beat any Intel in any kind of workload.

The ASRock A520M ITX/ac is one of the most expensive A520 boards at $105. In fact in many markets it might be the most expensive. That would be a little unusual for ASRock which is normally known for its highly competitive bang for buck offerings. It’s one of few A520 boards to include WiFi though, so that alone adds a great deal of usefulness. It supports a speed of 433 Mbps, not exactly the Usain Bolt of WiFi speeds when Wifi 6 is the norm, but it’s enough for high speed internet.
The A520M ITX/ac includes an 8-phase DRMOS VRM with 60a chokes. Spec wise this is surprisingly good for an A520 board. The only real concern is the very small heatsink. We wouldn’t try overclocking a Ryzen 9 3950X with liquid nitrogen on this board, but a smart pairing of a 65W CPU with a bit of PBO for good measure won’t present any issue, as long as you have good case airflow.
Being an ITX board, there are only two RAM slots, but with support for up to 64GB, this isn’t a problem. Would even a single user ever pair more than 64GB with a $100 board anyway? The supported speeds are what matters. There are none of the silly arbitrary 2,666MHz B460 memory limitations here. You can run up to DDR4-4600 if you really want, though you’re better off sticking to 3600MHz with current Ryzen 3000 CPUs. Though that is rumoured to be changing with the Zen 3 CPUs loving DDR4-4000 by all accounts.
The M.2 heatsink is solid and sturdy and it’s well placed to benefit from air passing over it towards a rear case fan. There are four SATA ports, standard fare on any ITX board where space is at a premium. Also noteworthy is the inclusion of RGB and ARGB headers. Fool your friends into thinking your $105 board is worth a lot more!
The rear I/O is fairly standard, with six USB ports consisting of two 2.0 ports and four 3.1 Gen 1 ports. We’d like to see eight on all but the very cheapest boards but the little ASRock is hardly alone there. We are pleased to see both HDMI 2.1 and Display Port 1.4 meaning that proper 4K/60Hz with a Renoir APU will be doable.
There’s also Realtek RTL8111H LAN and ALC887 audio. The ALC887 chip is over 10 years old now and is a bit lacking compared to the ALC 1200 found on the Gigabyte A520 Aorus Elite. If proper HiFi is high on your list of priorities, you can do better.(Image credit: ASRock) System performance Image 1 of 6 Image 2 of 6 Image 3 of 6 Image 4 of 6 Image 5 of 6 Image 6 of 6 Gaming performance Image 1 of 4 Image 2 of 4 Image 3 of 4 Image 4 of 4 Test rig

As we often say, the performance of modern motherboards usually falls within a standard margin of error. If we see an outlier, it can often be attributed an aggressive multi core turbo mode or even ambient temperatures affecting GPU boost clocks. The ASRock performed as expected. We did note that its storage performance with a Samsung 970 Pro was strong.
The gaming differences were minimal as expected. There’s nothing really stopping you from pairing the A520 ITX with a high quality GPU, no matter if you’re looking to push a high refresh rate monitor or game with all the eye candy at 4K.
The inclusion of WiFi alone makes this little ASRock one of the few compelling genuinely affordable ITX options. If you paired it with something like a Ryzen 3300X then you could divert some of your budget towards a better graphics card or bigger SSD. It’s also great to have upcoming Ryzen 5000 series CPU compatibility. If we are to believe AMD, a 65W 5600X sounds like a pretty sweet upgrade!(Image credit: ASRock)
Just make sure you update your BIOS before popping one in.
It won’t blow up if you install a 105W CPU, and it will do almost everything a board at twice the price will do, that is if you don’t care about 7,000MB/s PCIe 4.0 SSD transfers.
The ASRock A520M's audio is a bit of a letdown but that’s something that budget boards often compromise on. A gamer listening to compressed audio assets in-game probably won’t be any less immersed.
The little ASRock A520M ITX/ac has it where it counts and will serve you well at the heart of a budget gaming system. It benefits from the strengths of the Ryzen platform and adds some future proofing into the mix. ITX fans looking for a capable budget AMD Ryzen option should definitely have this one on their shortlist.
